I have been a recruiter, OIC of officer programs recruiting, and senior augment to a Recruiting District CO. The Navy does not target "poor" neighborhoods. It is a business decision. Spending time and money in a market that produces a very small percentage of qualified applicants of the greater pool of candidates is a waste. In actuality, enlisted recruiters target the best high schools in their assigned area. Debate why it is the case and possible solutions, but the fact is, most high schools in the poor neighborhoods imagined here are academicly crappy. The kids are more likely to be medically unqualified as well. There is no percentage in targeting poor people. Recruiting Command targets the highest quality applicants they can get, informed by diversity interests.
